This bit of css will center a 1 pixel tall bar in its container. I change its width to indicate progress of something loading.
#centered_bar {
display: block;
margin-left: auto;
margin-right: auto;
top: 100px;
height: 1px;
position: relative;
background-color: #FFFFFF;
}
How would I make the left and right edge of this element 'fade' (so, when zoomed in, the edge would look like the bottom line-end in this picture)?
This would be something similar to a gradient fill and would be subject to some browser compatibility issues so your best best is using a JavaScript library like CSS3Pie, and animate the appropriate property with jQuery or something similar.
I would start here: http://css3pie.com/documentation/supported-css3-features/#gradients
Good luck!

I'm building a website for our church and I'm using joomla 2.5 to do so. The template i used was wsnone2. I know a bit of code but not a lot i've tried to play around to sort out this issue but i cant seem to do it. Basically when there is very few lines of text as here http://www.smass2.co.uk/index.php/en/hymns/annual/deacon-responses/liturgies the footer comes up and covers the space. How do i stop that without making the position fixed. i tried using ryanfait sticky footer, and several others, but that didnt seem to work. can anyone people provide me with any more suggestions? if possible could the solution be done through CSS?
Thanks.
Actually, this is going to be harder than it looks at first glance. You have a couple things working against you here. First, your footer is actually contained in 2 divs, region9wrap and region10wrap. Doing as #gartox suggests will only move part of the footer to the bottom of the page. You would also need to do the same for the other part. To do so you would need this CCS -
.region9wrap {
color: #999;
position: fixed;
left: 0px;
bottom: 30px; /* height of div below*/
width: 100%;
}
.region10wrap {
color: #999;
position: fixed;
left: 0px;
bottom: 0px;
height: 30px;
width: 100%;
}
That will move both parts of the footer down, but now you will have a huge dark stripe where your background does not extend to the footer. Now you have to fix the background. First you need to remove the background from region4wrap completely.
Then add the background to the body tag -
body {
background: url('http://www.smass2.co.uk/images/Cross.jpg') no-repeat #0D0D0D;
}
This will make the background extend all the way down to the footer of the page without causing a big dark stripe.
You need do this:
In the class .region10wrap add this properties:values
.region10wrap
color: #999;
position: fixed;
left: 0px;
bottom: 0px;
height: 30px; /* your height footer*/
width: 100%;
}
Easiest way to do this is to have the footers background on the actual page (behind the whole site), so when the footer can't reach the bottom, it will look like it's stretching all the way down.
This is my first question, I don't think I'm doing something wrong asking it, as it's specific, I'm trying to do a gallery, this gallery has pages, each of which has a caption, I need to show an image with 16:9 ratio and the caption no matter how long it's.
As it's right now, it can show the caption, but when we resize the browser to a smaller breakpoint, if the caption is too long it will just break (will show the caption but maybe not the image if the caption is too long).
That's the solution I'm looking for right now, I'll leave a jsfiddle as an example, I tried to make it the simplest possible, so don't look at the ugly arrows and stuff :P.
fiddle: http://jsfiddle.net/Vb7bP/5/
An ugly fix for this would be to change the padding-bottom here:
.galleryContainer {
padding-bottom: 56.25%; // This is for the image to respect a 16:9 aspect ratio.
}
But that won't work cause it might break if the caption is too long or too short, we might loose our 16:9 ratio.
The caption css I think is fine, it's positioned at the bottom of the div as absolute.
.galleryCaptionWrapper {
background: #ccc;
width: 100%;
position: absolute;
padding: 25px;
z-index: 3;
bottom: 0;
}
Any kind of help will be much appreciated, sorry if the question is wrong. Thanks!
Is this what you're looking for?

I think you had absolute positioning on a lot of things where you didn't need it. Pertinent css is here:
.galleryImageWrapper {
background-color: #000;
width: 100%;
padding-bottom: 56%;
position: relative;
}
.galleryImageWrapper img {
position: absolute;
width: 100%;
top: 0;
left: 0;
height: 100%;
}
I had a similar question myself:
Scaling object element height proportional to width + constant with CSS
You don't have to do anything special to make the caption come after the image. That's the standard behavior for block elements.
Working with a Wordpress theme, and needed to have the blue blur background stay with the slider when the browser window is re-sized. I have achieved that goal, but I have noticed that when you narrow the browser, everything does not stay centered there is a large space on the left. What would be the best way to remedy this?
http://www.stringcreative.ca/wp/
The sites a bit of a mess, you need to have the wrappers with the image, then the containers the same size centered
#wrapper {
background: #000b1a url("http://www.stringcreative.ca/wp/wp-content/themes/Rbox2Pro/images/masthead.jpg") no-repeat fixed top center;
}
#header_container {
margin: 0 auto;
height: 117px;
width: 960px;
position: relative;
}
dont need a lot of the position's set to absolute, and margins at - to get it to fit.
also look into the 960 Grid System. i use it all the time, and saves me loads of time getting the site to fit. hope this helps
It's because your solution for centered the slider is inelegant, and relies on fixed widths and absolute positioning to make it look right.
To fix it, you need to change a few things.
Change #homebgw to:
#homebgw {
background: url("http://www.stringcreative.ca/wp/wp-content/themes/Rbox2Pro/images/masthead.jpg") no-repeat scroll 50% -117px transparent;
height: 411px;
width: 100%;
}
Change #header to:
#header {
background: url("http://www.stringcreative.ca/wp/wp-content/themes/Rbox2Pro/images/masthead.jpg") no-repeat scroll 50% 0;
height: 100px;
margin: 0 auto;
padding-bottom: 35px;
width: 1400px;
}
Quite simply, you don't need absolute positioning to solve the issues you posted above. If you're using absolute positioning and negative margins to correct center alignment issues, you're probably doing something wrong. Keep it simple, and Google how to achieve the results you desire. The net is full of helpful documentation to achieve these basic results without hacking up your code with fixes ;)
I have a div within a div. I want one to extend out of the shell div so it resembles a tab. I thought just using absolute positioning with a negative value would push it out of the parent div. That doesn't seem to work. Is there a CSS work-around?
Example
http://jsfiddle.net/W3CyT/
http://jsfiddle.net/iambriansreed/W3CyT/4/
CSS
#sideWall {
height:100px;
width:100px;
position:absolute;
top: 10;
left: 10;
background: black;
margin-top: 60px; /* give room for tab */
}
.showSideWall {
height: 60px;
width: 30px;
position: absolute;
top: -60px; /* move tab above container */
right: 0;
background: red;
}
You're doing it correctly, however, you need to rethink your values for bottom and right.
If you're looking to have the red box protrude from the black box on its right side, consider removing right:0 and applying left:100% instead. This approach guarantees that no matter how wide the black box and red box are, the red box will always be on the outside to the right; they are width-size agnostic. This can be ideal because you may want to change the size of either box dynamically or in the future (it doesn't lock you in to hard set values).
Here's a fiddle of what I'm talking about.
You could use a Z-Index and position one on top of another. There is a better way to do it with Twitter bootstrap code.

they give you templates for all kinds of cool features
I have a square div of fixed size and wish to place an arbitrary size image inside so that it is centred both horizontally and vertically, using CSS. Horizontally is easy:
.container { text-align: center }
For the vertical, the common solution is:
.container {
height: 50px;
line-height: 50px;
}
img {
vertical-align: middle;
}
But this is not perfect, depending on the font size, the image will be around 2-4px too far down.
To my understanding, this is because the "middle" used for vertical-align is not really the middle, but a particular position on the font that is close to the middle. A (slightly hacky) workaround would be:
container {
font-size: 0;
}
and this works in Chrome and IE7, but not IE8. We are hoping to make all font lines the same point, in the middle, but it seems to be hit-and-miss depending on the browser and, probably, the font used.
The only solution I can think of is to hack the line-height, making it slightly shorter, to make the image appear in the right location, but it seems extremely fragile. Is there a better solution?
See a demo of all three solutions here:
http://jsfiddle.net/usvrj/3/
Those without IE8 may find this screenshot useful:
If css3 is an option, then flexbox does a good job at vertical and horizontal aligning:
UPDATED FIDDLE
.container {
display:flex;
align-items: center; /* align vertical */
justify-content: center; /* align horizontal */
}
How about using your image as a background? This way you could center it consistently everywhere. Something along these lines:
margin:5px;
padding:0;
background:url(http://dummyimage.com/50) no-repeat center center red;
height:60px;
width:60px;
This is REALLY hacky, but it is what we used to do in the ie6 days.
.container {
position: relative;
}
img {
position: absolute;
top: 50%;
left: 50%;
margin-top: -12px; // half of whatever the image's height is, assuming 24px
margin-left: -12px; // half of whatever the image's width is, assuming 24px
}
I may be missing something in this example, but you get the idea.
Have you tried the following:
img {
display: block;
line-height: 0;
}
I usually use this hack, but I haven't really checked it that thoroughly in IE8.
Here is a small JS Fiddle I have made: http://jsfiddle.net/rachit5/Ge4YH/
I believe it matches your requirement.
HTML:
<div>
<img src=""/>
</div>
CSS:
div{height:400px;width:400px;position:relative;border:1px solid #000;}
img{position:absolute;top:0;left:0;right:0;bottom:0;margin:auto;}
